Germanium Ore Concentrating

Germanium Statistics and Information

Germanium Statistics and Information

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayishwhite element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium
